IPC: F16D23/14
Filed: 1967-03-16
Abstract: A friction clutch is engaged by a diaphragm spring 5 and disengaged by a release sleeve 8 axially slidably mounted in a guide sleeve 7 welded to a clutch cover 2, the sleeve 8 being shifted to the right to disengage the clutch by a fork 13 acting through a bearing 10.

Title: Voltage control circuit for a-c generator subject to widely varying drive speeds
IPC: H02J7/14
Filed: 1967-06-14
Abstract: The output voltage of a permanent magnet generator 10 providing a D.C. supply on lines 23, 24 by way of a full wave rectifier including thyristors 18, 19, 20 is regulated by a system including oscillators 40, 41, 42, which produce firing pulses for the respective thyristors 18, 19, 20 and switching means for switching the oscillators on and off in appropriate phase relation to the commencement of the cycle of the generator alternating voltage. As shown, for oscillator 40 a voltage dependent upon D.C. output voltage variations is derived from a comparator 43 and is superimposed on a sawtooth voltage derived from one phase X by way of a capacitor 62 and resistors 59, 56 and 63 this combined voltage is compared at transistor 48 with a reference voltage derived from a Zener diode 33 and the resultant effect causes oscillator 40 to produce firing pulses for the thyristor 18, the phase angle of these pulses, relative to the cycle of alternating voltage applied to the thyristor, varying in dependence upon output voltage variations. The thyristors 19 and 20, connected to phases Z and Y of the generator, are similarly controlled by the oscillators 41, 42, whereby the D. C. output of the generator is maintained constant. The sawtooth producing circuit may be constituted by the series combination of an inductor and resistor Fig. 7 (not shown), and the oscillators may be astable multi-vibrators. One of the thyristors, e.g. 18 as shown, may have connected in parallel with it the series combination of a rectifier 30 and the normally closed contact 28 of a relay 27, the relay being connected so that the contact 28 opens when the D.C. output voltage exceeds a specific value this arrangement allows a pulsating direct voltage to appear between lines 23, 24 when the generator is started up from rest, causing the oscillators 40, 41, 42 to oscillate and thus the thyristors 18, 19, 20 to be fired.

Patent ES-367888-A1 (ES)
Title: Method and apparatus for controlling one oscillator by another
IPC: G04G3/02
Filed: 1969-05-30
Abstract: A method of controlling the frequency of a sinewave oscillator 6 by means of a higher frequency oscillator 3 comprises: sensing the attainment of a peak value of a parameter of the oscillation of oscillator 6 clamping the, parameter at this peak value to temporarily inhibit oscillation and releasing the clamp when the oscillator 3 next reaches a datum in its oscillation cycle. As described, the peak value of the current through inductor 8 is sensed by detecting the corresponding passage through zero of the voltage across capacitor 7. When this zero crossing occurs, trigger circuit 10, 11 switches to produce an output pulse which turns on transistor 18 via transistor 12. Transistor 18 then feeds to inductor 8 a current which is equal to the peak value of the oscillatory current. The high-frequency oscillator 3 provides a train of pulses, and the arrival of the next pulse in this train turn on transistor 19 to switch off transistor 18 and allow the oscillator 6 to recommence oscillation.
Patent ES-382602-A1 (ES)
Title: Ignition distributors
IPC: F02P7/06
Filed: 1970-08-08
Abstract: A method of assembling an ignition distributor including the steps of engaging an annular timing plate with an annular base plate so that the timing plate is capable of angular movement with respect to the base plate. Three ears formed on the base plate overlie the timing plate, and the timing plate is rotated relative to the base plate, so that three ramps provided on the timing plate engage the ears respectively. As the timing plate is rotated the ramps bend the ears away from the timing plate, so that a clearance exists between the ears and the timing plate which is substantially equal to the heights of the highest part of the ramps above the surface of the timing plate. Thus the timing plate will be capable of a predetermined degree of axial movement relative to the base plate.

Patent ES-438166-A1 (ES)
Title: Chemical process
IPC: C07C17/00
Filed: 1975-06-03
Abstract: Saturated organic compounds containing a hydrogen atom bound to a tertiary carbon atom may be electrophilically fluorinated by reaction with an electrophilic fluorinating agent such as molecular fluorine or trifluoromethyl hypofluorite under conditions whereby the formation of free fluorine radicals is suppressed, e.g. by the presence of a free radical inhibitor such as oxygen or nitrobenzene, the reactants being substantially homogeneously dispersed in a liquid medium, e.g. a solvent medium such as fluorotrichloromethane or chloroform/fluorotrichloromethane, so that the said hydrogen atom is electrophilically replaced by a fluorine atom. The fluoroination is highly selective and, in the case of complex substrates such as saturated steroids which contain a number of tertiary C-H bonds, may be substantially completely confined to replacement of the hydrogen atom at the tertiary carbon atom which has the highest electron density about the C-H bond. The electron density and thus the direction of the fluorination may be controlled by appropriate selection of substituent groupings in the substrate molecule.
